Engine needs a new head gasket. Country Auto Clinic diagnosed #4 as the issue. Truck has a block heater, spray-in bed liner (8ft box), goose-neck ball, brake controller, backup siren, tool box and fire extinguisher. It had new rear leaf springs installed at 103,800 miles. This truck spent most of it's life sitting idle at the mines in Mercer county hence the low miles. Has dual gas tanks. If you have questions, I respond quickest to text. Thanks for looking.
